                             EMPLOYMENT AGREEMENT

         AGREEMENT dated as of January 6, 1998 between William J. Rouhana,
Jr., residing at 22 Anchor Way, Port Washington, NY 11050 ("Executive"), and
WINSTAR COMMUNICATIONS, INC., a Delaware corporation having its principal
office at 230 Park Avenue, Suite 2700, New York, New York 10169 ("Company").

         WHEREAS, the Company and Executive entered into a three (3) year
employment agreement on March 1, 1995 which will terminate on February 28,
1998 (the "1995 Agreement"); and

         WHEREAS, the Company believes that Executive provides unique
management services for the Company and wishes to retain the continued
services of Executive as its Chairman and Chief Executive Officer; and

         WHEREAS, the Company and Executive have reached an understanding with
respect to the extension of Executive's employment with the Company for an
additional three (3) year period from the date of termination of the 1995
Agreement; and

         WHEREAS, the Company and Executive desire to evidence their agreement
in writing and to provide for the employment of Executive by the Company on
the terms set forth herein;

                  IT IS AGREED:

         1.   Employment, Duties and Acceptance.

              1.1 Effective as of March 1, 1998 ("Renewal Date") the Company
hereby agrees to the continued employment of Executive as its Chairman of the
Board and Chief Executive Officer and Executive hereby accepts such continued
employment on the terms and conditions contained in the Agreement. During the
term of this Agreement, the Executive shall make himself available to the
Company to pursue the business of the Company subject to the supervision and
direction of the Board of Directors of the Company ("Board" or "Board of
Directors") of which he shall be nominated to be a member during the term
hereof.
<PAGE>

              1.2 The Board may assign to Executive such general management
and supervisory responsibilities and executive duties for the Company as are
appropriate and commensurate with Executive's position as Chairman and Chief
Executive Officer of the Company ("CEO") and would otherwise be consistent in
stature and prestige with the responsibilities of the chief executive officer
of a corporation with operations as the incumbent certified local exchange
carrier of telecommunications in the five principal markets (based on
population) in which the Company's subsidiaries are licensed to provide
telecommunications services. The Executive shall serve as Chairman of the
Executive Committee of the Board (if such a committee is established) and all
other officers of the Company shall report to him and be subject to his
supervision and control.


              1.3 Executive accepts such employment and agrees to devote
substantially all of his business time, energies and attention to the
performance of his duties; provided, however, that Executive may continue to
be actively involved in eleemosynary, educational and civic activities to the
extent that such activities do not materially detract from the reasonable
performance of his duties, as expressed by a resolution approved by the
majority of the Board and a written notice to Executive, in which event
Executive shall have one hundred and twenty (120) days to reduce the level of
such activities in a reasonable manner. The Company recognizes the value to it
of Executive's continued involvement in these activities and will reimburse
Executive for reasonable expenses incurred by him in connection with such
activities. Nothing herein shall be construed as preventing Executive from (i)
making and supervising investments on a personal or family basis (including
trusts, funds and investment entities in which the Executive or members of his
family have an interest) and (ii) in serving on the Board of Directors of not
more than three corporations involved primarily in business activities
provided, however, that these activities do not materially interfere with the
performance of his duties hereunder or violate the provisions of Section 4.4
hereof.

         2.   Compensation and Benefits.

              2.1 The Company shall pay to Executive a salary at an annual
base rate of not less than $537,000 for each of the first three consecutive
twelve-month periods during the term hereof commencing March 1, 1998 and
ending February 28, 2001. Executive's salary will be paid not less frequently
than every two weeks without the prior written consent of Executive.
Executive's annual base rate will be reviewed not less frequently than
annually on or before February 1 during the term hereof for purposes of
determining appropriate annual increases therein.

              2.2 The Company shall also pay to Executive such bonuses as may
be determined from time to time by the Compensation Committee of the Board of
Directors. The amount of annual bonus payable to Executive may vary at the
discretion of the Compensation Committee of the Board of Directors provided,

                                     -2-

<PAGE>

however, that the total bonus shall not exceed 150% of Executive's annual base
rate under Section 2.1 as of the date of the bonus is awarded. No employee of
the Company shall be entitled to receive an aggregate salary and bonus higher
than Executive for any year without the unanimous approval of the Board (other
than the Executive). In determining the annual bonus to be paid to the
Executive, the Compensation Committee may, among other factors they believe to
be appropriate, consider, and give varying degrees of importance to, the
Executive's contribution to the following:

     a)   the attraction and retention of key executive personnel by the
          Company
     b)   satisfaction of the Company's capital requirements
     c)   the establishment of strategic direction and significant Company
          goals

     d)   achievement by the Company of specific identified targets selected
          by the Committee from time to time
     e)   growth in the Company's per share value
     f)   increase in the Company's "Enterprise Value". (For purpose hereof,
          "Enterprise Value" means (a) the total number of common shares, on a
          fully diluted basis, times the then current market price of the
          common shares plus (b) the principal amount of all outstanding
          non-convertible debt and the designated liquidation amount of any
          mandatorily redeemable non-convertible preferred stock plus (c) cash
          and cash equivalents of the Company minus the scheduled proceeds
          (cash, reduction in debt and preferred stock liquidation value) of
          all rights, warrants, options and convertible securities assuming
          complete exercise or conversion thereof.)

              2.3 As additional compensation for services to be rendered by
Executive hereunder, the Company shall issue to Executive options to purchase
900,000 shares of Common Stock under the 1995 Performance Equity Plan which
options shall vest in accordance with the following two sentences except for
certain acceleration events as set forth in the Stock Option Agreements or
this Agreement. These options ("Agreement Options") shall be evidenced by
three (3) Stock Option Agreements of even date herewith between the Company
and Executive. Five hundred thousand (500,000) of the Agreement Options will
have an exercise price of $26.00 per share and will vest 300,000 on the
Renewal Date and 100,000 on each anniversary date thereof. Two hundred
thousand (200,000) of the Agreement Options will have an exercise price of
$39.00 per share and will vest on the first anniversary date of the Renewal
Date and the final two hundred thousand (200,000) of the Agreement Options
will have an exercise price of $52.00 per share and will vest on the second
anniversary date of the Renewal Date.

              2.4 Executive shall be entitled to such insurance and other
benefits including, among others, medical and disability coverage and life
insurance as are afforded to other senior executives of the Company, subject
to applicable waiting periods and other conditions which may be generally
applicable. The Company also shall purchase (i) long term disability insurance
of not less than 50% of Executive's than current annual salary and (ii) split
dollar life insurance with coverage of not less than $1.5 million. The
beneficiary of these policies shall be designated by Executive and these
policies shall be transferred to Executive or his designees by the Company at
his written request.

                                     -3-

<PAGE>

              2.5 Executive shall be entitled to five weeks of vacation in
each calendar year and to a reasonable number of other days off for religious
and personal reasons. In addition, Executive shall be entitled to ten working
days paid sabbatical (which need not be consecutive) during each year for
involvement in eleemosynary, educational and/or civic activities.

              2.6 Executive shall also be required, at Company cost, in order
to allow Executive to focus on work activities and communicate with the
business while in transit, to utilize a car and driver with mobile telephone

to travel to and from the Company's offices and his principal residence within
forty-five (45) miles of New York City and when traveling on Company business,
to and from the point of demarcation on other forms of transportation for such
traveling and when traveling to other meetings on Company business.

              2.7 The Company will pay or reimburse Executive for all
transportation, hotel and other expenses incurred by Executive on business
trips (including first class air travel when traveling on a scheduled flight
of more than two (2) consecutive hours) and for all other ordinary and
reasonable out-of-pocket expenses actually incurred by him in the conduct of
the business of the Company against itemized vouchers submitted with respect
to any such expenses.

              2.8. Executive agrees that his services shall be rendered
primarily at the Company's executive offices which shall be located in, or
within thirty (30) miles of, New York City provided, however, that Executive
may maintain an office adjacent to his residence and shall be reimbursed for
all costs reasonably related thereto (including secretarial assistance,
telephone, fax, computer and other communications equipment) by the Company.

         3.   Term and Termination.

              3.1  The term of this Agreement commences as of March 1, 1998 and
shall continue until February 28, 2001, unless sooner terminated as herein
provided.

              3.2 If Executive dies during the term of this Agreement, this
Agreement shall thereupon terminate, except that the Company shall pay to the
legal representative of Executive's estate the base salary due Executive
pursuant to Section 2.1 hereof through the first anniversary of Executive's
death (or the scheduled expiration under Section 3.1, if earlier than the
first anniversary date) as well as a pro rata allocation of bonus payments
under Section 2.2 based on the days of service during the year of death.

              3.3 If Executive shall be rendered incapable by an
incapacitating illness or disability (either physical or mental) of complying
with the terms, provisions and conditions hereof on his part to be performed
for a period in excess of 180 consecutive days during any consecutive twelve
(12) month period,

                                     -4-
<PAGE>

then the Company, at its option, may terminate this Agreement by written
notice to Executive (the "Disability Notice") delivered prior to the date
Executive resumes the rendering of services hereunder provided, however, if
requested by Executive (or a representative thereof) such termination shall
not occur until after examination of Executive by a medical doctor (retained
by the Company with the consent of the Executive which consent shall not be
unreasonably withheld) who certifies in a written report to the Board with a
copy of such report delivered simultaneously to Executive that Executive is
and shall be incapable of performing his duties for in excess of two
additional months because of the continuing existence of such incapacitating
illness or disability. Notwithstanding such termination, the Company (a) shall

make a payment to Executive of a pro rata allocation of payments under Section
2.2 based on the days of service during the year in which the Disability
Notice is delivered and (b) shall pay to Executive the base salary due
Executive pursuant to Section 2.1 hereof through the second anniversary of the
date of such notice (the "Disability Period"), less any amount Executive
receives for such period from any Company-sponsored or Company-paid for source
of insurance, disability compensation or government program. At the
Executive's request, the Company shall provide to Executive at the Company's
expense an office for his exclusive use in New York City at the Company's
principal executive offices with full time confidential secretarial assistance
and office services during the Disability Period.

              3.4 The Company, by notice to Executive, may terminate this
Agreement for cause. As used herein, "cause" shall include (a) the refusal in
bad faith by Executive to carry out specific written directions of the Board,
(b) intentional fraud or dishonest action by Executive in his relations with
the Company ("dishonest" for these purposes shall mean Executive's knowingly
making of a material misstatement to the Board for the purpose of obtaining
direct personal benefit); or (c) the conviction of Executive of any crime
involving an act of significant moral turpitude after appeal or the period for
appeal has elapsed without an appeal being filed by Executive. Notwithstanding
the foregoing, no "cause" for termination shall be deemed to exist with
respect to Executive's acts described in clause (a) or (b) above, unless the
Board shall have given written notice to Executive (after five (5) days
advance written notice to Executive and a reasonable opportunity to Executive
to present his views with respect to the existence of "cause"), specifying the
"cause" with particularity and, within twenty (20) business days after such
notice, Executive shall not have (i) disputed the Board's determination or in
reasonably good faith taken action to cure or eliminate prospectively the
problem or thing giving rise to such "cause," provided, however, that (i) any
periodic breach or continual breaching after notice and cure of any provision
of clause (a) or (b) above; or (ii) a repeated breach after notice and cure,
of any provision of clause (a) or (b) above, involving the same or
substantially similar actions or conduct, shall be grounds for termination for
cause upon not less than five (5) days additional notice from the Company.

              3.5 In the event of a dispute as to the existence of suitable
"cause" for termination pursuant Section 3.4, Executive shall be entitled to
file for arbitration of such dispute in New York City in

                                     -5-
<PAGE>

accordance with the rules of the American Arbitration Association with one
arbitrator to be selected by the Company and one arbitrator to be selected by
the Executive, and pending final determination of such arbitration
proceedings, Executive shall continue to be compensated and shall be
reimbursed for his expenses including his legal costs in accordance with the
terms of this Agreement.

              3.6 The Company may terminate this Agreement at anytime without
cause, upon ninety (90) days advance notice to Executive; provided, however,
that the Company shall continue to pay Executive without diminution, his base
salary pursuant to Section 2.1 and bonuses pursuant to Section 2.2, through

the later of (ii) two years after termination and (iii) the third anniversary
of this Agreement and Executive shall have no obligation of any nature to
mitigate such payment. All outstanding options held by him in the Company
shall irrevocably vest upon such termination. During such period, the Company
shall also provide to Executive at the Company's expense an Executive office
(equivalent to the office provided to him at the time of termination) for his
exclusive use in New York City at the Company's principal executive office, or
at such other location as may be agreed to by Executive, with full time
confidential secretarial assistance and office support. If Executive is at any
time not a member of the Board of Directors of the Company and a member of the
Executive Committee thereof (if such a committee then exists), the Executive
at his election shall be deemed to have been terminated by the Company without
cause and the provisions of this Section 3.6 shall apply provided, however,
that this sentence shall not be applicable if the reason therefor (other than
for termination under Sections 3.2, 3.3 or 3.4) is Executive's written
voluntary election to resign from the Board or any such committee.

         4.   Protection of Confidential Information; Non-Competition.

              4.1 Executive acknowledges that:

                   (a) As a result of his current employment with the Company,
Executive will obtain secret and confidential information concerning the
business of the Company and its subsidiaries and affiliates (referred to
collectively in this Article 4 as the "Company"), including, without
limitation, financial information, designs and other proprietary rights, trade
secrets and "know-how," customers and sources ("Confidential Information").

                   (b) The Company will suffer substantial damage which will
be difficult to compute if, during the period of his employment with the
Company or thereafter, Executive should enter a business competitive with the
Company or divulge Confidential Information.

                   (c) The provisions of this Agreement are reasonable and
necessary for the protection of the business of the Company.

                                     -6-
<PAGE>

              4.2 Executive agrees that he will not at any time, either during
the term of this Agreement and for a period of one year thereafter, divulge to
any person or entity any Confidential Information obtained or learned by him
as a result of his employment with the Company, except (i) in the course of
performing his duties hereunder, (ii) to the extent that any such information
is in the pubic domain other than as a result of Executive's breach of any of
his obligations hereunder, (iii) where required to be disclosed by court
order, subpoena or other government process or (iv) if such disclosure is made
without Executive's knowing intent to cause material harm to the Company. If
Executive shall be required to make disclosure pursuant to the provisions of
clause (iii) of the preceding sentence, Executive promptly, but in no event
more than 72 hours after learning of such subpoena, court order, or other
government process, shall notify, by personal delivery or by electronic means,
confirmed by mail, the Company and, at the Company's expense, Executive shall:
(a) take reasonably necessary and lawful steps required by the Company to

defend against the enforcement of such subpoena, court order or other
government process, and (b) permit the Company to intervene and participate
with counsel of its choice in any proceeding relating to the enforcement
thereof.

              4.3 Upon termination of his employment with the Company;
Executive will promptly deliver to the Company all memoranda, notes, records,
reports, manuals, drawings, blue-prints and other documents (and all copies
thereof) relating to the business of the Company and all property associated
therewith, which he may then possess or have under his control; provided,
however, that the Executive shall be entitled to retain one copy of such
documents for his personal use and records.

              4.4 During the period commencing March 1, 1998 and terminating
on the first to occur of (i) one year after termination for cause, and (ii)
one year after termination without cause (or one month if such termination
results from the failure of the Company to renew Executive's employment upon
scheduled expiration of this Agreement): (A) Executive, without the prior
written permission of the Company (which, after three months following
termination for cause, shall not be unreasonably withheld), shall not,
anywhere in the United States of America, (i) enter into the employ of or
render any services to any person, firm or corporation engaged in any business
which is directly in competition as a licensee of 38 GHz spectrum with the
Company's principal existing wireless telecommunication business at the time
of termination ("Competitive Business"); (ii) engage in any Competitive
Business as an individual, partner, shareholder, creditor, director, officer,
principal, agent, employee, trustee consultant, advisor or in any other
relationship or capacity; (iv) employ, or have or cause any other person or
entity to employ, any person who was employed by the Company at the time of
termination of Executive's employment by the Company (other than former
employees or shareholders of WC, as herein defined, and Executive's personal
secretarial assistant); or (v) solicit, interfere with, or endeavor to entice
away from the Company, for the benefit of a Competitive Business, any of its
customers. Notwithstanding the foregoing, Executive shall not be precluded
from investing and managing the investment of, his or his family's assets in
the securities of any

                                     -7-
<PAGE>

corporation or other business entity which is engaged in a Competitive
Business if such securities are traded on a national stock exchange or in the
over-the-counter market and if such investment does not result in his
beneficially owning, at any time, more than 5% of any class of the
publicly-traded equity securities of such Competitive Business; provided,
however, that for a period commencing March 1, 1998 and terminating one year
after termination of Executive's employment (except for investments in a class
of securities trading on public markets), Executive shall refer to the Company
for consideration (before any other party) any and all opportunities to
acquire or purchase, or otherwise make equity or debt investments in,
companies primarily involved in a Competitive Business if such opportunity
becomes known to Executive while he is the Chairman and Chief Executive
Officer of the Company. If the Company determines not to exploit any
opportunity referred to in the foregoing sentence, the Company shall determine

what, if anything, should be done with such opportunity. Executive shall not
be entitled to any compensation, as a finder or otherwise, if either the
Company or Executive introduces such opportunity to other persons, it being
understood that all such compensation shall be paid to the Company.
Notwithstanding the foregoing, in the event the Company terminates this
Agreement without cause under Section 3.6 hereof, Executive's obligations
under this Section 4.4 shall terminate one month following termination unless
the Company fails to make payment of salary pursuant to Section 3.6 hereof for
more than two (2) days after payment would normally be made in which case,
Executive's obligations under this Section 4.4 shall immediately terminate.

              4.5  If Executive commits a breach of any of the provisions of
Sections 4.2 or 4.4, the Company shall have the right;

                  (a) to have the provisions of this Agreement specifically
enforced by any court having equity jurisdiction, it being acknowledged and
agreed by Executive that the services being rendered hereunder to the Company
are of a special, unique and extraordinary character and that any breach or
threatened breach will cause irreparable injury to the Company and that money
damages will not provide an adequate remedy to the Company; and

                  (b) to require Executive to account for and pay over to the
Company all monetary damages determined by a non-appealable decision by a
court of law to have been suffered by the Company as the result of any actions
constituting a breach of any of the provisions of Sections 4.2 or 4.4, and
Executive hereby agrees to account for and pay over such damages to the
Company (up to the maximum of all payments made under the Agreement).

              4.6 If Executive shall violate any covenant contained in Section
4.4, the duration of such covenant so violated shall be automatically extended
for a period of time equal to the period of such violation.

                                     -8-

              4.7 If any provision of Sections 4.2 or 4.4 is held to be
unenforceable because of the scope, duration or area of its applicability, the
tribunal making such determination shall not have the power to modify such
scope, duration, or area, or all of them and such provision or provisions
shall be void ab initio.

         5.   Miscellaneous Provisions.

                           Attn:  General Counsel

              5.2 Executive represents and warrants to the Company that he is
not party to any agreement which would restrict him from entering into this
Agreement or performing hereunder. The Company agrees to reimburse Executive
for all costs, expenses and other amounts reasonably incurred by him in
connection with the defense, settlement or other payments of any claims,
investigations, suits or other actions ("Prior Claims") arising out of his

officer or director thereof and his determination to become an executive of
the Company, to enter into the 1995 Agreement or to terminate prospectively
the WinStar Services, Inc. Consulting Agreement as of February 28, 1995

that he breached any existing agreement or arrangement prohibiting his
employment by the Company.

              5.3 In the event of any claims, litigation or other proceedings
arising under this Agreement (including, among others, arbitration under

(30) days after delivery to the Company of statements for the costs incurred
by the Executive in connection with the analysis, defense and prosecution
thereof, including reasonable attorneys' fees and expenses provided, however,

damage to the Company in connection with any such claim, litigation or
proceeding.

              5.4 The Company shall to the fullest extent permitted by law

simultaneously herewith set forth the entire agreement of the parties relating
to the employment of Executive and are intended to supersede all prior
negotiations, understandings and agreements. No provisions of this Agreement
or the Stock Option Agreements may be waived or changed except by a writing by
the party against whom such waiver or change is sought to be enforced. The
failure of any party to require performance of an provision hereof or thereof
shall in no manner affect the right at a later time to enforce such provision.

Agreement, and the rights and obligations of the parties hereunder, shall be
determined in accordance with the law of the State of New York applicable to
